Abstract: eXtensible Access Control Markup Language (XACML) standardised by OCG was widely used in the area of information security. And recently geospatial XACML was standardised. But now, types of information are diversified. Especially, importance of information about time and space is continually increased. We use information to know where or when we do something. For instance, we usually check time or find the way with it. Therefore, Geospatial eXtensible Access Control Markup Language (GeoXACML) is not enough to cover it. In this paper, we propose that spatio-temporal XACML which can accept not only geospatial information but also temporal information. Spatio-temporal XACML is based on and expands standardised GeoXACML in OCG. Its scenario consists of access control between positions of polices.
